As a relatively new player for faceless in a region dominated by swarm i can understand the OP.
However, judging from the numbers i see here on a regular basis i think you are asking a bit much.
My idea would be the opposite approach.
Why not add a weapon with extremely short range, let's say like 5km that acts like a bomb and make it much stronk? That would add some serious home advantage. Or alternativley make attack formations lose power over range (exclude nanos and plasma). Maybe something like that would allow newcomers to at least get a foothold in their homezones. It's just an idea, maybe i overlooked something?
